Last year Cobra released the
Trailblazer series of GMRS radios.
Gratefully, they continued to use the same privacy codes as they have previously used.
That means the mappings between brands of radios that I describe in my
FRS/GMRS Privacy Codes Demystified
deep dive work great with the Cobra Trailblazer 250, 450, and 500.

Zero Retries has recently moved to a new publishing
platform and domain. If you haven't updated your email subscription or missed the
transition, it's easy to resubscribe to this outstanding free email newsletter.
Continuing the momentum from last year, Steve and Tina Stroh are planning the second
annual Zero Retries Digital Conference
on October 16, 2026 in San Ramon, CA. ZRDC will be held in the same city, and on the
same day as the first day of Pacificon 2026. You can attend
two great conferences in a single trip.
Tina is putting together the speakers and presentations, I can't wait what she comes
up with.
Save the date, registration will be open soon, and they expect tickets to go quickly.

There are many digital modes in amater radio. The ones popular on handheld
VHF/UHF radios include:
- D-Star
- DMR
- System Fusion
- NXDN
- P25
To use these modes you typically need two things:
- a handheld radio that supports the mode you want to use
- a nearby repeater or reflector that supports the mode you want to use
There are many options for handheld radios. These repeaters are usually
connected to the internet which enables communications with others around the
world using that same mode. If there isn't a repeater in your area that
offers the digital mode you want to use, you are out of luck. Unless you have a
hotspot.
A hotspot is a pocket sized low power repeater that connects to the internet
and can communicate with your handheld using various digital modes. You can buy
commercial devices, or build your own with a Raspberry Pi, radio boards, and
open source software.
The Hamspot 5 by Collin K0NNK is a new option
which gives you the flexibility and upgradability of your own Raspberry Pi based
solution, without you having to do all the tinkering to get something that
works.
This looks like a great device, with full duplex operation and a nice looking
case. Runs from USB-C power, and connects to the internet via Ethernet or Wi-Fi.
